Guys,
I made a list by grepping and perling around in the source.
grep -Pr "c(.)(\s+)switch_channel_set_variable\(channel, \"" * | grep -v "Binary" > /tmp/chan_vars.tmp
This gave me a massive list of all filenames and occurrences of “switch_channel_set_variable” with a channel variable explicitly named in quotes.
I then filtered out stuff with svn in the source filename and then create a tab-separated list of chan variables and source filenames. Finally, I distilled that list with this script:
perl -n -e 'm/(\w+)\t(.*)/;next if (exists($seen{$1}));print $1 . "\t" . $2 . "\n";$seen{$1}=$2;' /tmp/chan_vars3.tmp
This yielded a nice list of variables. Let me know what you think about using this as the base list for channel variables on the wiki:
